Description
Technical field:
The utility model relates to a kind of seal arrangement, relates in particular to a kind of ultrahigh pressure antiscale mechanical seal device.
Background technique:
At present, in oil recovery field, oil field, the ultrahigh pressure water injection pump generally adopts soft packing seal; Because ultrahigh pressure water injection pump WATER AS FLOW MEDIUM is impure more, be prone to fouling, chemical substance is complicated; Seriously corroded makes sealing short device lifetime, and leakage rate is big; Axle and axle sleeve serious wear are changed frequently, and the string quantity of motion of operation axis is big.Because often leakage can make the water inlet of bearing shell lubricant oil, cause being influenced ordinary production by forced-stopping machine, when maintenance, labor intensity of operating staff is big.Add front-mounted pump at the inlet front end simultaneously and feed liquid systems, during the water injection pump operation, inlet pressure 1.6MPa, outlet pressure 16～22MPa, the existing mechanical sealing configuration has satisfied not the usage requirement of ultrahigh pressure water injection pump.
The model utility content:
The purpose of the utility model provides a kind of ultrahigh pressure antiscale mechanical seal device, and it has the advantages that the life-span is long, leakage rate is little and axle does not does not wear and tear with axle sleeve.
In order to solve the existing problem of background technique; The utility model is to adopt following technological scheme: it comprises pump cavity 1, axle 2, axle sleeve 3, rotating ring 4, flow guide type gland 5, stationary ring 6, throw-out collar 7, spring seat 8, spring 9, anti-rotation pin 10, is equipped with cap 11, short cover 12, seal ring 13, flushing hole 14, pod apertures 15 and overflow hole 16; Axle 2 outer walls are fixed with axle sleeve 3 and rotating ring 4 successively; Axle sleeve 3 outsides are socketed with pump cavity 1; Pump cavity 1 bottom is fixed with flow guide type gland 5, is disposed with stationary ring 6, throw-out collar 7 and spring seat 8 between flow guide type gland 5 and axle sleeve 3, the rotating ring 4 from top to bottom, and rotating ring 4 contacts with stationary ring 6 end faces; Be provided with spring 9 and anti-rotation pin 10 between throw-out collar 7 and the spring seat 8; The bottom of axle 2 is fixed with short cover 12 and seal ring 13 through being equipped with cap 11, and flushing hole 14 is arranged on the pump cavity 1, and pod apertures 15 is arranged on the flow guide type gland 5 with overflow hole 16; And pod apertures 15 communicates with flushing hole 14, and pod apertures 15 communicates with the cavity that flow guide type gland 5, throw-out collar 7 and spring seat 8 form.
Described stationary ring 6 outer surfaces are provided with the antiscale layer.
Described spring seat 8 circumferentially is evenly distributed with several springs 9 and anti-rotation pin 10.
The motive sealing of the utility model axle head is to adopt the surface of contact of rotating ring and stationary ring to fit tightly to seal, and sealing state is stable, does not have to leak.Its water output improves 1.5%, and 1～1.5 ton of day water saving had both reduced cost, had improved the efficient of pump again.Long service life, but general stable operation more than 1 year, the annual pump electricity charge 3～50,000 yuan of having practiced thrift, friction horsepower reduces, and power consumption descends 0.5%, day economizes on electricity 80～100 to spend.In use axle and axle sleeve do not need to change, and maintenance man's labor intensity reduces, and has improved working environment.
